Capture Style Sheet Properties In Variable?
Sep 27, 2009
I would like to create a function that will change the colour of a button when clicked then change it back at the end of the function. It works by capturing the backgroun color an then storing it as a variable. However it refuses to capture the original background color if the style is set via an external CSS style sheet. It only works if i set the style via the element markup. Am i doing something wrong and is there any way of capturing the style set by a external stylesheet?
Code:
function myFunction(el)
{
[code]....

I thought I'd try to begin with the accordion and tab, but I have had no success yet. I must be missing something simple. Here is the first test page:[code]Instead of getting tabs, I get my pages (generated by cgi perl scripts) displayed in tiny little scrollboxes at the top left.Equally bad, Firefox is telling me, in the error console, that jQuery.Tabs is undefined.FireFox doesn't like the filter and zoom properties in your style sheet.So, then, what do I need to do to get the tabs to work in the first instance. And then, how do I modify it to use an Accordion to display the same material. Are there any issues I need to be aware of when I start having my perl scripts (using predominantly the Perl packagesCGI and CGI::Session)create these pages?As far as possible, I am trying to keep this all valid HTML5, so that I can eventually make this interface mobile device friendly.

I'm writing a reusable JavaScript library which needs to set certain styles in a document. The document may have an existing stylesheet definition either by a link or by an existing stylesheet declaration in the documents head section.
How can I use JavaScript to append my own style sheet information to a possibly already existing stylesheet definition?

It seems it's impossible to get a css style position from an external style sheet with JS, no?
<p id="testParagraph"></p>
if external css was:
p {
position: relative;
left: 20px;
}
apparently js cannot get
document.getElementById("testParagraph").style.left;
It seems it must be set as an inline css in the html or set by js explicitly in order to return the value. I don't get WHY it doesn't work.

I have a script that works perfectly on a live site that basically has a menu that reveals a hidden DIV and when you click a link, and then when you click a new link it hides the previous div and reaveals the new one. It is as follows:
Javascript Code:
Original - javascript Code
LastLayer = "nothing"; // the first div/layer
function openObject(theLayer){
// pass the name of the layer you want to bring to the top
// Then hide the last layer, and make the layer passed visible. This could have been done using the z-index property
if (document.getElementById) { // if it's IE5 or NS6 use this syntax to access the visiblity attribute
eval("document.getElementById(LastLayer).style.visibility = 'hidden'")
eval("document.getElementById(theLayer).style.visibility = 'visible'")
LastLayer = theLayer;
}
if(document.layers) { // if it's NS4 use this syntax to access the visiblity attribute
eval('document.layers[LastLayer].visibility = "hidden"')
eval('document.layers[theLayer].visibility = "visible"')
LastLayer = theLayer;
} .....
Now I am redesigning the site to work with a new style sheet, (There wasn't one before, it was all inline styles. Anyway, it broke my script. The CSS has a class that gives certain DIV's visibility attribute the 'hidden' value by default. I was planning on using the above script to reveal/hide them, but it does nothing. Here is the CSS that affects the divs I am referring to.
CSS Code:
Original - css Code
.job {
border: thin solid #000000;
float: right;
margin-right: 25px;
padding-left: 10px;
width: 40%;
display: none;
}
.job { border: thin solid #000000; float: right; margin-right: 25px; padding-left: 10px; width: 40%; display: none;}
As you can see there is nothing fancy in the css that would cause any concern.

I have found a solution for showing an element on page load (it should be hidden if JS is blocked), but the CSS and the JS go into the <head>. I prefer to keep all such code in external files, so how do I adapt it to support that approach? Found code is as follows (if it can be improved on, feel free to say so):
Code:
<script type="text/javascript">
document.write('<style type="text/css">#myDiv {display: block;}</style>');
</script>

I am using the stylesheet switcher on dynamic drive . Is there a way to change stylesheets based on a querystring parameter? Basically, if the query string includes "&StyleSheet=BlueStyle" then call and set the BlueStyle.css and cookie on page load.

i've designed a site using firefox as my primary browser. (note: i'm on an old mac so limited to only what i can run on 10.2.8) i tweaked it for safari, and then took the stuff on a jump drive to the library and tweaked it for IE6 on a pc.
what i need to do now is either hack the CSS for safari and ie (and eventually others once i get some feedback); or, use javascript to load the correct style sheet.
i've just spent two days--thursday and today since since 10 a.m.--trying to figure out first the js, and then the hack methods to no avail. (well, more, really over the past few weeks, but the two-day immersion has me totally fried.)
i'm reached the point where time is extremely critical. once i get this out in an acceptable form, i can spend more time on the learning curve.
here is the document head code:

I am working on a little javascript project, and I need to get an arbitrary element's style information.
For instance, I want a method that you can pass a reference to an object, and for instance, find the current css height property that applies to it, no matter where it was declared. I don't mind it returning a null value if it wasn't set anywhere, but if it's coming from some css class or some css id or some locally defined style, I want to know what is being expressed.
If I just try el.style.height, it only lets you know what the height is if it was explicitly defined in the style tag.

Using Javascript I know you can create elements on the page, but is it possible to create properties within the Style element?
For instance, I want to create the following CSS style:
Code:
.className
{
background-color: #9cf;
border-top: 2pt solid #000;
border-right: 1pt solid #000;
border-bottom: 1pt solid #000;
border-left: 1pt solid #000;
}
Is this possible using the DOM, or will I need to export all of my styles in one long text string and replace the Style tags innerHTML?

I find I often have to change links in templates. I work for someone who is always wanting to alter their links. Is it possible to create a global template, or "master document" to link to as you would in a style sheet? This is what I want to do: Have 1 document that contains links. When I make changes to this document, all links on all pages would change also.

I was originally under the impression that css style properties could
be accessed/ listed since they exsisted as an array somewhere.
Is this just flat out wrong?
To illustrate - I guess I thought something like this could be used to
list available/ or set properties, or in this example the first
property. Is this just a fantasy? Or how does this work, at this level
or for document objects even?
//assuming <div id="menu"></div> exisists and hs styles applied....
document.write(document.getElementById('menu').sty le[0]);
//of course this is wrong...

I'm not sure this is the right group to post to, I've just found this group.I notice the old alt.dhtml group has been murdered, overwhelmed by spam. On my page: [URL] I am trying to get an element's style.top, style.marginTop, and backgroundColor. I can successfully do getElementById( ) on the element, but I can't get any settings from the element. If you bring up the page, all of this stuff is supposed to display in a header-like line just under the small banner. I can see that the doc's scrollTop has been retrieved OK (it wiggles if you move the vertical scroll bar) but all the other stuff is MIA. What am I doing wrong that I can't get this element's style properties? In the source, the function 'scroll(),' which is trying to read these
properties, is at line 52.

I know the atomic way to set style properties of a DOM element like
Is there any way to set multiple properties in the same time? I'd like to spare some cpu time...
I assume if I use framework like JQuery to set more style props at once that call will be interpreted to the atomic way I described above...
Am I right with this guess?

how to add extra properties to html elements as I was storing data in html attributes. After looking at some others code including Raphael and this addEvent code. [URL] They seem to treat objects just like an array. obj[property] = value; This would have been extremely helpful to know previously as I have needed to be able to include variables in property names - but have resorted to making the whole thing a string and calling exec() on it.
